What's Changed
❗ Breaking changes
CID in CAR block keys and CID DAG-CBOR are now in raw byte form instead of stringified one!
⚡ Bunch of new optimizations
- Optimize duplicate check by@MarshalX in#34
- Optimize type checking by@MarshalX in#37
- Optimize keys duplication check by@MarshalX in#39
- Optimize array creation by@MarshalX in#40
- Optimize string encoding by@MarshalX in#41
🆕 Features
- Add CID encoding (
encode_cid(bytes) -> str) by@MarshalX in#38 - Add DAG-CBOR profiling by@MarshalX in#35
Other
- Fix upload to PyPI by@MarshalX in#33
- Update CodSpeed to v3 by@MarshalX in#47
- Update PyO3 to 0.22.2 by@MarshalX in#48
- Lock rust toolchain on v1.76.0 because higher versions segfaults during PGO gather by@MarshalX in#46

I highly recommend using Python 3.12. The lower version will be slower.
P.S. Breaking change not only gives a performance boost but also aligns implementations with other languages.
